i Application led October 16, 1918. Serial No. 258,469.

To all whom t may concern:

Be it known that I, WILLIAM J. BARBER, citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain ne-W and useful Improvements vin Gas-Burners, of which the following is a specification.

The invention herein is an improvement on my patent of May 28, 1918, No. 1,267,355, in which the nature of this style of burner is fully set forth.

In the accompanying drawings, Figure 1 is a perspective view of my new and improved burner, and Fig. 2 is a plan view thereof. Fig. 3 is a side elevation with one of the burner units cross sectioned and with shorter elbows than in Fig. 1.

In this burner as a whole I show four distinct and individual units 18, which are substantially U shape and cast together about a common center With connecting webbing at their inner or bent ends 19. In disposition about said center the units are set at right angles 'to each other and the outer ends of all the branch pipes are alike closed by. means of a screw plug 20, and

said ends in each unit are also connected by' A boss 21 is cast on the bottom of one branch in each unit relatively near the bent innerV portion 19 and an elbow pipe 22, or its equivalent as to shape and length is screwed into each boss and has a supply pipe 23 connected therewith. The said supply pipes are in turn connected with a manifold 24, having separate valves 25 adapted to control the flow of gas to each unit, so that in operation one or more burners may be used according to the heat wanted.

The said units are preferably disposed on radial lines from their common center, and

4the supply pipes 23 run parallel to each other 1n the same plane but in angular relation to the units, thereby permitting each' unit to be tapped in a corresponding place by the vertical supply pipe connection 22.

All the units alike have relatively small gas orifices 26 at intervals drilled at an inwardly inclined angle in respect to each other in each unit so' as to project the streams of issuing gas on converging lines. The yangles of inclination may be somewhat varied but inclinations say from thirty to forty five degrees to the perpendicular are preferred, and the branches of each unit are spaced apart far enough to permit a free flow of air upwardly between them into the angle of convergence of the gas to insure what I regard as perfect combustion.

A pilot light may, if preferred, be placed in the center of the burner to effect ignition. but I have found that such a light is not absolutely necessary in view of the fact that any one of the units can be turned down very low and serve this purpose.

In this connection it is to be especially observed that this type of burner does not employ a mixer, so-called, and that combustion depends exclusively on the commingling of air in the open with the gas at its confluence from the opposite jets. Furthermore, with this construction of burner it is possible to maintain a heating flame with V less pressure of gas in the main than by any other lStyle of burner of which I have any knowledge, and with exceptional economy under normal pressure conditions.

What I claim is:

Aygas burner,'comprising a plurality of U-shaped pipe units radially arranged with their corresponding U-bent ends lying closely adjacent to each other about a common center and' separate gas supply pipes connected with said units adjacent to their bent ends, and the spaced branchesof each unit having oppositely-disposed gas orifices inclined toward each other at intervals to provide converging jets of gas centrally above the air space between such branches. f

Signed at Cleveland, in the county of Cuyahoga. and State of Ohio, this 11th day ofJuly, 1918.

WILLIAM J. BARBER.
